长波红外双组联动连续变焦光学系统设计

Design of a Long Wave Infrared Double-Linkage Continuous Zoom Optical System

研究了双组联动长波红外连续变焦光学系统设计,设计了工作波段为7.7.m^9.5.m,焦距为30mm^360mm,F数为2.24的双组联动连续变焦光学系统,设计结果表明,成像质量好,在331p/mm空间频率处的调制传递函数值均超过0.15。

We investigated long-wave,infrared,double-linkage,continuous-zoom optical systems and designed a double-linkage continuous-zoom optical system for the 7.7 m^9.5 m waveband.The focal length is 30 mm^360 mm and the F number is 2.24.The results demonstrate that the system has high imaging quality,with a modulated transfer function value greater than 0.15 at 33 lines/mm spatial frequency in the image plane.
